Lead-Free Tapware in New Zealand
From 2 May 2026, updated requirements under G12/AS1 Amendment 14 apply to certain copper alloy plumbing products used in contact with drinking water.
Relevant products must have a weighted average lead content of no more than 0.25%. The requirements apply to products such as taps, mixers, valves, fittings, water heaters and other plumbing products used in contact with drinking water.
What Does Lead-Free Mean?
Under G12/AS1 Amendment 14, copper alloy products used in contact with drinking water must have a weighted average lead content of ≤ 0.25%.
Compliance can be demonstrated through recognised product certification or testing, including testing to NSF/ANSI/CAN 372:2020 by an IANZ-accredited or equivalent internationally accredited testing facility.
​
Which Products Are Covered?
The requirements apply to a range of plumbing products used in contact with drinking water, including taps and mixers, copper alloy fittings, valves, water meters, water heaters and certain other water supply products.
Some products are excluded from the lead-free provision, including showers and baths used for bathing, including shower and bath mixers, as well as products used exclusively for non-potable water applications.
​
How Can I Identify Lead-Free Products?
Customers can check product specifications, Building Product Information Requirements (BPIR) documentation, recognised certification markings or accredited test reports.
MBIE also advises homeowners to look for LF (Lead-Free) and DR (Dezincification Resistant) identification where applicable.
